To all whom it may concern.

Be it known that I, JAMES B. MAYBERRY, a citizen of the United States, residing at Shreveport, parish of Caddo, and State of Louisiana, have invented a certain new and useful Improvement in Link Cups for Chain Pumps, of which the following is a specification.

My invention relates to a construction of link cups to be employed in chain pumps for raising liquid from wells. It is particularly adapted for use in deep wells where a strong device is necessary, but manifestly is adaptable for use in wells of any depth.

It is an object of the invention to provide a bucket link for use in chain pumps which is strong in construction and has a maximum carrying capacity.

It is also desired to provide a cup which can be easily assembled into a chain for pumping purposes and which is automati cally locking when assembled.

It is also an object to so construct a link cup of the character statedthat it will not become tangled when in use and which may be easily and cheaply manufactured.

Referring to the drawing herewith, Fig. 1 is a side elevation of a section oi bucket chain employing my invention, certain parts being broken away for greater clearness; Fig. 2 is a side elevation taken at right angles to the view shown in Fig. 1', one link being shown in central longitudinal sec tion; Fig. 3 is a transverse section on the plane 3-3 of Fig. 1 and Fig. 4 is a side elevation of one of the parts of my improved bucket links. -Like numeralsof reference designate like parts in all the views.

My invention is adapted to be employed in connection with bucket pumps. and pertains particularly to the construction of the link which forms the bucket forcarrying the fluid. Such a bucket must be strong in construction and adapted to sustain a heavy weight constituting the load carried by the link itself, and in the other links below it during its progress out of the well. In the drawing I have illustrated a bucket made up of two plates, 1, identical in construction, adapted to fit together on one side thereof to provide a spherical bucket for the carrying of liquid. The plates 1 are made hemispherical at the central portion 2 forming the body of the bucket. On each end of the hemispherical central portion are formed laterally extending hooked plates 3.

One end of the bucket is intended to be presented upwardly as the chain is com ing out of the well. This upper end is provided with a plurality oi openings 5 therein to allow the entrance and outlet of oil or water or other fiuid'being pumped. Along the central vertical axis of the plates forming the bucket, the hooked end is curved or bent to one side, as shown at 6 in-Fig. 3, so that the cooperating portion. of the bucket may fit resiliently therein and thus automatically latch the two cooperating parts in position. In Figs. 1 and 2 the two plates making-up the bucket are shown in assembled position The end plates 3 are bent,

slightlyout of the plane of the central portion of the bucket at'Z, as shown particularly in Fig. 2, so that the end of the opposite engaging plate may fit against the same, causing the two ends to interlock.

In assembling a bucket of this kind, two plates forming the bucket are placed together with the faces of the hemispherical container contacting accurately together. A link 8 is engaged within the hooked end i at each end of the plate, and the parts are then rotated to cause the ends 3' to fitv to gether so as to include the link as shown in Fig. 1. When the ends are brought together, the curved portions 6 are forced one 7 over the other, so that they will interenand be held resiliently in position. While the chain is extended, as shown in Figs. 1 and 2, the link 8 will assist in holding the two parts of the bucket link together, and absolutely prevent the parts from becoming unlatched.

The two side plates making. up the bucket link may be stamped out of sheet steel in large quantities, and may be made to fit'accurately together so that there will be no leakage between the two parts forming the sphere. It is possible, however, to place a circular gasket or packing ring between the two plates along their contacting margins so that leakage will be absolutely prevented when the two parts are latched together. The link 8 securing two adjacent bucket linkstogether'may be formed of the usual type of linkordinarily employed in chains.

It will therefore be possible toform these bucket links cheaply and supply them in large quantities to the trade at reasonable prices. The spherical form of the bucket link provides a device which will not easily be caught or hung up on other parts of the apparatus or with other links. A chain made of this form will not become tangled when it is loosened, and may be employed in the pumping operation without special precaution for its safety. It is easily adaptable for use upon an operating type .ofs rocket wheel without danger of being it '3 injured or mutilated in its operation. It has a maximum carrying capacity and will take on and discharge the liquid through the openings 5 without difliculty, and there will be little danger of loss of fluid due to movement or vibration of the chain while i1 use. I

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is: s

1. A cup for chain pumps comprising a pair of coengaging plates, the intermediate portions of which fit together to form a liquid container, and oppositely extending hooked ends on each plate formed to overlap and frictionally engage the hooked end c t-the opposite plate and to include the end of an adja ent connecting link for the purpose described.

2. A cup for chain pump comprising a pair of coengaging plates having cupped members intermediate the ends thereof. said cupped members being adapted to fit together to form a container for fluid. oppositely-extending curved ends on each plate formed to frictionallv engage the ends of the opposite plate, said pair of plates when engaged forming openings at each end thereof to receive the adjacent connecting link.

3. A cup for chain pumps comprising a pair of coengagina plates, the central portion of each plate being depressed outwardly to form a hemispherical. cup having openings in the upper end thereof, longitudinally extending ends on each plate shaped to interlock with the ends of the opposite plate whereby a central spherical container is formed. the ends of plates of which are adapted to engage the adjacent link and be releasably locked thereto.

4. A cup for chain pumps comprising a pair of coengaging plates, each plate having a central curved cup member adapted tofit in fluid-tight relation with the opposite plate to form a liquid container having liquid ports therein,longitudinally extending ends on each ofsaid plates grooved to interfit resiliently with the opposite coengaging plate, said ends forming, when said cup is assembled, ameans of attachment to the adjacent Connecting member in the chain.
